Description
Alanazi, Alanzi, and Abdo map the proof on matcha and green tea for stress hormones in twenty twenty-six. Ads claim these drinks calm stress and aid hormone health, but studies use quite unlike products. Whole leaf matcha, brewed tea, and single pure compounds are often lumped as one. The team sorted studies by a ratio of the drink's key compounds.
Twenty-two studies with about seven hundred people were kept. Drinks with a low ratio were most often tied to calmer stress responses. No human trial of matcha tracked both key hormones at once, a plain gap. Proof grades were low or very low. The team sets a clear agenda for sharper trials.
